Inspired by DYPLED, this Wristwatch Uses BPW34 PIN Photodiodes, Supercapacitor for Power
Peter Misenko’s wristwatch is one-of-a-kind with a 25x8mm 3V 5F supercap as the power source, mounted in such a way that the backplate of the watch is essentially flat (and surprisingly thin!):
Check out the full wristwatch project here and the DYPLED project that inspired this build (and perhaps your next thin LED display project!) here.
5 years of watch development in one master piece of hardware
Features:
– BPW34 solar cells … plastic, small, unbreakable
– ultra High effective step up converter 95% wint minimum 0.4V working voltage
MAX1724 – Thanks for samples form Maxim Integrated
– custom led 4014 display, inspired by https://hackaday.io/whygeehttps://hackaday.io/project/8693-dypled project
– Supercapacitor capacity gauge
– Supercapacitor can be charged with USB or SUN

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
